Bad experience with this shop. they could not fix a bad wheel bearing in my s 10 pickup. after 15 hundred dollars and 2 rear ends.. no results , I decided to take my s10 to another shop which was fixed in 2 hours at less then 5 hundred dollars. The other shop found a front wheel bearing bad..NOT a bad rear end these guys were trying to fix. I dealt with Knittels for some time with favorable results but lately they seem to have lost there good mechanics. I lost money with problem not fixed and I have NO 4 wheel drive or parking brakes now. not sure when I lost my 4 wheel drive..
